keymaps weren't being set in keymay.cfg of cbfs, due
to use of x_ in the rom script, and x_ doesn't handle
quotes or spaces in arguments well.
i'm going to remove use of x_ and xx_ (it's in my todo),
for next release.
for now, hot patch the release. i've gone through and
replaced use of x_ with || err, in some places.
not just the keymap.cfg command, but others too. in case
there are more issues we missed.
this commit is being tagged "20231021fix" and i'm using
this tag to re-build the 20231021 release. i'll just
replace the tarballs in rsync and add errata to the news
page announcing the release. all i did was break peoples
umlauts, i didn't brick their machines fortunately!
very minor bug. anyway, x_/xx_ is a great idea, but sh
isn't really designed for that style of programming. i'll
go back to using just || err in the next release.
